The influence of a defendant's body weight on perceptions of guilt.

OBJECTIVE: To investigate the influence of a defendant's weight on simulated jurors' perceptions of guilt. DESIGN AND METHODS: Participants were 471 lean and overweight adults (mean body mass index: 25.34±5.91) who read a vignette describing a case of check fraud while viewing one of four images of the alleged defendant (a lean male, a lean female, an obese male or an obese female). Participants rated the defendant's culpability on a 5-point Likert scale and completed measures of anti-fat attitudes. RESULTS: Male respondents endorsed greater overall weight bias than females (F (1470)=23.815, P<0.01, η(2)=0.048). A three-way interaction was detected between participant sex, defendant sex and defendant weight on perceptions of guilt such that when the defendant was female, male participants were significantly more likely to find her guilty if she was obese than if she was lean (guilt ratings=4.05±0.83; 3.31±1.03, respectively; F(1467)=5.935, P=0.015, R(2)=0.060). In addition, lean male participants were significantly more likely to believe that the obese female defendant met criteria for check fraud, and indicated greater belief she would be a repeat offender, compared with the lean female defendant (t(90)=2.081, P=0.040; t(90)=2.395 P=0.019, respectively). There were no differences in perceptions of guilt or responsibility between the obese male and the lean male defendants. CONCLUSION: The results of this novel study indicate that both weight and gender of a defendant may affect juror perceptions of guilt and responsibility.

Does perception asymmetrically influence motor production in upper and lower visual fields?

The authors examined if previously reported anatomical asymmetries between the upper (uVF) and lower visual fields (lVF) influence the preparation and control of visually and memory-guided reaching movements. To manipulate visual field, participants maintained their visual gaze on a cue position presented above or below the location of a target object, thus resulting in reaches completed in respective uVF and lVF of peripersonal. In Experiment 1, participants performed reaches to four targets with indices of difficulty ranging from 3.1 to 5.1 bits under five visual-memory conditions: full vision and memory-guided conditions entailing 0, 2, 5, and 10 s of delay. In Experiment 2, participants reached to the vertex of Müller-Lyer figures in 3 visual-memory conditions: full vision, and memory-guided conditions entailing 0, and 2 s of delay. In accord with duplex theories of vision (e.g., Milner & Goodale, 1992), it was hypothesized that the introduction of a visual delay and/or the introduction of context-dependent illusory structure would differentially bias the efficiency and effectiveness of uVF and lVF reaches. Although data displayed mixed supported for the existence of an lVF advantage for movement execution, neither the introduction of delay nor contextual illusions succeeded in differentiating visual fields. Thus, performance advantages for movements made in the lower visual field do not appear associated with preferential connections to parietal (i.e., dorsal-action) and temporal (i.e., ventral-perception) architectures.

Eighty-five per cent of what? Discrepancies in the weight cut-off for anorexia nervosa substantially affect the prevalence of underweight.

BACKGROUND: DSM-IV cites <85% of expected body weight (EBW) as a guideline for the diagnosis of anorexia nervosa (AN) but does not require a specific method for calculating EBW. The purpose of the present study was to determine the degree to which weight cut-off calculations vary across studies, and to evaluate whether differential cut-offs lead to discrepancies in the prevalence of individuals who are eligible for the AN diagnosis. METHOD: Two coders independently recorded the EBW calculation methods from 99 studies that either (a) compared individuals with AN to those with subclinical eating disorders or (b) conducted AN treatment trials. Each weight cut-off was applied to a nationally representative (n=12001) and treatment-seeking (n=189) sample to determine the impact of EBW calculation on the proportion who met the AN weight criterion. RESULTS: Coders identified 10 different EBW methods, each of which produced different weight cut-offs for the diagnosis of AN. Although only 0.23% of the national sample met the lowest cut-off, this number increased 43-fold to 10.10% under the highest cut-off. Similarly, only 48.1% of treatment seekers met the lowest cut-off, whereas 89.4% met the highest. CONCLUSIONS: There is considerable variance across studies in the determination of the AN weight cut-off. Discrepancies substantially affect the proportion of individuals who are eligible for diagnosis, treatment and insurance reimbursement. However, differences may not be fully appreciated because the ubiquitous citation of the 85% criterion creates a sense of false consensus.

Perceptions of weight discrimination: prevalence and comparison to race and gender discrimination in America.

OBJECTIVE: Limited data are available on the prevalence and patterns of body weight discrimination from representative samples. This study examined experiences of weight/height discrimination in a nationally representative sample of US adults and compared their prevalence and patterns with discrimination experiences based on race and gender. METHOD AND PROCEDURES: Data were from the National Survey of Midlife Development in the United States, a 1995-1996 community-based survey of English-speaking adults aged 25-74 (N=2290). Reported experiences of weight/height discrimination included a variety of institutional settings and interpersonal relationships. Multivariate regression analyses were used to predict weight/height discrimination controlling for sociodemographic characteristics and body weight status. RESULTS: The prevalence of weight/height discrimination ranged from 5% among men to 10% among women, but these average percentages obscure the much higher risk of weight discrimination among heavier individuals (40% for adults with body mass index (BMI) of 35 and above). Younger individuals with a higher BMI had a particularly high risk of weight/height discrimination regardless of their race, education and weight status. Women were at greater risk for weight/height discrimination than men, especially women with a BMI of 30-35 who were three times more likely to report weight/height discrimination compared to male peers of a similar weight. DISCUSSION: Weight/height discrimination is prevalent in American society and is relatively close to reported rates of racial discrimination, particularly among women. Both institutional forms of weight/height discrimination (for example, in employment settings) and interpersonal mistreatment due to weight/height (for example, being called names) were common, and in some cases were even more prevalent than discrimination due to gender and race.

Introduction of the multiple mini interview into the admissions process at the University of Calgary: acceptability and feasibility.

The MMI was introduced into the medical admissions process at the University of Calgary (UofC) in 2006. This report outlines the steps which were involved in its development and our evaluation of the process. The MMI allowed us to interview applicants in one weekend, with fewer interviewers and less time required per interviewer compared to our previous interview process. Most importantly, more than 90% of both the applicants and interviewers found the process to be very acceptable. This process allowed us to ensure that the interview process focused on the non-cognitive traits we are looking for in the students we admit to the UofC.

Acetylcholine receptor antibodies in myasthenia gravis are associated with greater risk of diabetes and thyroid disease.

OBJECTIVE: Myasthenia gravis (MG) may be associated with the presence of acetylcholine receptor antibodies (AChRAb) [seropositive MG (SPMG)] or their absence [seronegative MG (SNMG)]. Along with features of MG, the presence of the AChRAb may relate to the existence of other immune-mediated diseases. We sought to determine the association of SPMG with other potential autoimmune diseases. METHODS: A retrospective evaluation of prospectively identified MG patients at a tertiary care center was performed, with patients separated into SPMG and SNMG. Prevalence of other immune-mediated disorders, as well as the epidemiology, sensitivity of diagnostic testing, and thymic pathology, was contrasted between both patient groups. RESULTS: Of the 109 MG patients identified, 66% were SPMG. SPMG was associated with a greater likelihood of significant repetitive stimulation decrement, the presence of either thymoma or thymic hyperplasia, and the presence of thyroid disease. In addition, all patients with a diagnosis of diabetes, concurrent with MG, were found to be SPMG. CONCLUSIONS: AChRAb and SPMG impart not only a distinctive clinical and electrophysiological phenotype of MG, but are also associated with the heightened presence of endocrinological disease.

The influence of the stigma of obesity on overweight individuals.

OBJECTIVE: To investigate the internalization of anti-fat bias among overweight individuals across a variety of attitudes and stereotypes. DESIGN: Two studies were conducted using the Implicit Association Test (IAT), a performance-based measure of bias, to examine beliefs among overweight individuals about 'fat people' vs 'thin people'. Study two also contained explicit measures of attitudes about obese people. SUBJECTS: Study 1 participants were 68 overweight patients at a treatment research clinic (60 women, 8 men; mean Body Mass Index (BMI) of 37.1+/-3.9 kg/m(2)). Study 2 involved 48 overweight participants (33 women, 15 men) with a BMI of 34.5+/-4.0 kg/m(2). RESULTS: Participants exhibited significant anti-fat bias on the IAT across several attributes and stereotypes. They also endorsed the explicit belief that fat people are lazier than thin people. CONCLUSION: Unlike other minority group members, overweight individuals do not appear to hold more favorable attitudes toward ingroup members. This ingroup devaluation has implications for changing the stigma of obesity and for understanding the psychosocial and even medical impact of obesity on those affected.

Psychosocial origins of obesity stigma: toward changing a powerful and pervasive bias.

Widespread bias and discrimination based on weight have been documented in key areas of living, including education, employment, and health care. This paper examines the social and psychological origins of this bias through a review and critique of theoretical and empirical literatures, and proposes how the field might best advance in the area of reducing stigma. Explanations for the development and reduction of weight stigma are examined with different theoretical approaches, including attribution theory and a social consensus model. Individual and sociocultural contributors to bias suggested by these approaches are highlighted. New directions are discussed in both the understanding and prevention of weight bias.

"Before and after" diet advertisements escalate weight stigma.

The stigma-producing effects of "before and after" diet advertisements on a healthy weight sample were examined. Subjects (n = 59) were exposed to a presentation containing either a "before and after" diet ad, or solely the "before" or "after" picture embedded in a different ad. Subjects were then given measures to assess negative attitudes and endorsement of stereotypes about overweight people. Across all subjects, strong implicit anti-fat bias was present. Subjects in the Before and After condition indicated that weight is more easily controllable than did subjects in either the Before Picture Only or the After Picture Only conditions. There were two moderating variables for this effect. Subjects who reported greater life satisfaction endorsed fewer anti-fat stereotypes, and those who enjoyed an emotionally close relationship with an overweight person were less biased. These results suggest that "before and after" diet ads enhance weight stigma and perpetuate damaging stereotypes.

Bias, discrimination, and obesity.

This article reviews information on discriminatory attitudes and behaviors against obese individuals, integrates this to show whether systematic discrimination occurs and why, and discusses needed work in the field. Clear and consistent stigmatization, and in some cases discrimination, can be documented in three important areas of living: employment, education, and health care. Among the findings are that 28% of teachers in one study said that becoming obese is the worst thing that can happen to a person; 24% of nurses said that they are "repulsed" by obese persons; and, controlling for income and grades, parents provide less college support for their overweight than for their thin children. There are also suggestions but not yet documentation of discrimination occurring in adoption proceedings, jury selection, housing, and other areas. Given the vast numbers of people potentially affected, it is important to consider the research-related, educational, and social policy implications of these findings.

Implicit anti-fat bias among health professionals: is anyone immune?

OBJECTIVE: To investigate whether negative implicit attitudes and beliefs toward overweight persons exist among health professionals who specialize in obesity treatment, and to compare these findings to the implicit anti-fat bias evident in the general population. DESIGN: Health care professionals completed a series of implicit and explicit attitude and belief measures. Results were compared to measures obtained from a general population sample. SUBJECTS: A total of 84 health professionals who treat obesity (71% male, mean age 48 y, mean body mass index (BMI) 25.39). MEASUREMENTS: Participants completed an attitude- and a belief-based lmplicit Association Test. This reaction time measure of automatic memory-based associations asked participants to classify words into the following target category pair. 'fat people' vs 'thin people'. Simultaneously, the tasks required categorization of words into one of the following descriptor category pairs: good vs bad (attitude measure) or motivated vs lazy (stereotype measure). Participants also reported explicit attitudes and beliefs about fat and thin persons. RESULTS: Clear evidence for implicit anti-fat bias was found for both the attitude and stereotype measures. As expected, this bias was strong but was lower than bias in the general population. Also as predicted, only minimal evidence for an explicit anti-fat bias was found. Implicit and explicit measures of the lazy stereotype were positively related although the attitude measures were not. CONCLUSION: Even health care specialists have strong negative associations toward obese persons, indicating the pervasiveness of the stigma toward obesity. Notwithstanding, there appears to be a buffering factor, perhaps related to their experience in caring for obese patients, which reduces the bias.

Stress may add bite to appetite in women: a laboratory study of stress-induced cortisol and eating behavior.

To date, there are few known predictors of stress-induced eating. The purpose of this study was to identify whether physiological and psychological variables are related to eating after stress. Specifically, we hypothesized that high cortisol reactivity in response to stress may lead to eating after stress, given the relations between cortisol with both psychological stress and mechanisms affecting hunger. To test this, we exposed fifty-nine healthy pre-menopausal women to both a stress session and a control session on different days. High cortisol reactors consumed more calories on the stress day compared to low reactors, but ate similar amounts on the control day. In terms of taste preferences, high reactors ate significantly more sweet food across days. Increases in negative mood in response to the stressors were also significantly related to greater food consumption. These results suggest that psychophysiological response to stress may influence subsequent eating behavior. Over time, these alterations could impact both weight and health.

Stress and body shape: stress-induced cortisol secretion is consistently greater among women with central fat.

OBJECTIVE: Excessive central fat puts one at greater risk of disease. In animal studies, stress-induced cortisol secretion has been shown to increase central fat. The objective of this study was to assess whether women with central fat distribution (as indicated by a high waist-to-hip ratio [WHR]), across a range of body mass indexes, display consistently heightened cortisol reactivity to repeated laboratory stressors. METHODS: Fifty-nine healthy premenopausal women, 30 with a high WHR and 29 with a low WHR, were exposed to consecutive laboratory sessions over 4 days (three stress sessions and one rest session). During these sessions, cortisol and psychological responses were assessed. RESULTS: Women with a high WHR evaluated the laboratory challenges as more threatening, performed more poorly on them, and reported more chronic stress. These women secreted significantly more cortisol during the first stress session than women with a low WHR. Furthermore, lean women with a high WHR lacked habituation to stress in that they continued to secrete significantly more cortisol in response to now familiar challenges (days 2 and 3) than lean women with a low WHR. CONCLUSIONS: Central fat distribution is related to greater psychological vulnerability to stress and cortisol reactivity. This may be especially true among lean women, who did not habituate to repeated stress. The current cross-sectional findings support the hypothesis that stress-induced cortisol secretion may contribute to central fat and demonstrate a link between psychological stress and risk for disease.

Studying intergenerational transmission of eating attitudes and behaviors: methodological and conceptual questions.

Associations between parent and child attitudes and behaviors related to eating and weight were examined among college-age men and women and their mothers and fathers (ns = 44, 47, 87, and 66, respectively). Parent attitudes and behaviors were assessed from the perspective of the parent and the student, and 2 pathways of influence were examined: modeling and direct criticism. In general, students' attitudes and behaviors were more strongly related to perceptions of their parents rather than to parents' own self-reports. There was more support for perceived direct criticism as a pathway of influence, particularly for daughters. Perceived criticism about eating and appearance had large associations with student attitudes and behaviors. Weight loss behavior was related to perceived criticism among daughters and to perceived paternal eating attitudes among sons. Results highlight important methodological and conceptual questions for intergenerational research.

Small taxes on soft drinks and snack foods to promote health.

Health officials often wish to sponsor nutrition and other health promotion programs but are hampered by lack of funding. One source of funding is suggested by the fact that 18 states and 1 major city levy special taxes on soft drinks, candy, chewing gum, or snack foods. The tax rates may be too small to affect sales, but in some jurisdictions, the revenues generated are substantial. Nationally, about $1 billion is raised annually from these taxes. The authors propose that state and local governments levy taxes on foods of low nutritional value and use the revenues to fund health promotion programs.

Body mass index, eating attitudes, and symptoms of depression and anxiety in pregnancy and the postpartum period.

OBJECTIVE: This report describes associations between body mass index (BMI; kg/m2), eating attitudes, and affective symptoms across pregnancy and the postpartum period in a sample of 64 women. METHODS: As part of a larger study, women were recruited during pregnancy and followed prospectively to 14 months postpartum. Measures included self-reported prepregnancy and 4-month postpartum BMI as well as pregnancy, 4-month, and 14-month postpartum eating attitudes (EAT), depressive symptoms (CES-D), and anxiety symptoms (STAI). RESULTS: During pregnancy, symptoms of depression or anxiety were not significantly correlated with concurrent eating attitudes or measures of BMI. However, at 14 months postpartum, measures of eating attitudes and both depression and anxiety symptoms were associated. Measures of BMI were associated with depressive and anxiety symptoms at both 4 and 14 months postpartum. Four-month eating attitudes and BMI predicted 14-month postpartum depressive symptoms, beyond pregnancy, and 4-month postpartum measures of affective symptoms. Results suggested that overweight women were at risk for elevated anxiety at 4 months and depressive symptoms at both 4 and 14 months postpartum. CONCLUSIONS: These results provide evidence for a significant, albeit moderate, relationship between BMI, eating attitudes, and symptoms of depression and anxiety in the postpartum period that are not present during pregnancy.

"Fearful cognitions associated with eating pathology" psychometric properties of a new scale.

The psychometric properties of a new scale that measures fearful cognitions associated with eating problems were explored, using two independent samples of undergraduate females. In Study 1, an exploratory factor analysis was conducted to revise and shorten the scale. Study 2 reproduced the factor structure and positive relationship between fearful cognitions and eating pathology. Additionally, regression analyses demonstrated discriminant and incremental validity, since the scale explained 27% of the variance in eating pathology, and was independent of the effects of anxiety and depression. Implications for treatment, and a cognitive model of fears associated with eating disorders are discussed.

Eating attitudes and behaviors in pregnancy and postpartum: global stability versus specific transitions.

Global changes in eating attitudes were examined prospectively across pregnancy and 4 months postpartum in a sample of 90 women. In addition, specific changes in dieting behavior and weight/shape satisfaction were assessed at 4 months postpartum for concurrent and retrospective time points. Measures included the Eating Attitudes Test (EAT) and weight/shape satisfaction in pregnancy and at 4 months postpartum, as well as prepregnancy, pregnancy, and postpartum weight loss efforts. While global EAT scores were stable across time, dieting scores (Factor I) increased between pregnancy and postpartum. Weight/shape satisfaction was higher in pregnancy, and satisfaction was related to EAT scores at 4 months postpartum but not during pregnancy. Prepregnancy dieters and nondieters were best discriminated by higher weights, elevated pregnancy dieting scores, and lower postpartum weight/shape satisfaction. Results emphasize the importance of looking beyond changes in global eating attitudes and behaviors to more specific eating concerns or behaviors. Lastly, the results have implications for identifying women at risk for eating- and weight-related concerns during this period of rapid physical change.

Marital status, marital satisfaction, and body image dissatisfaction.

OBJECTIVE: This study examined whether married individuals have comparable body image disturbance to nonmarried individuals and whether the quality of a marital relationship is significantly related to body image disturbance in a sample of dieters. METHOD: Measures of marital status, marital satisfaction, and body dissatisfaction were administered to a sample of 16,377 subjects who had tried to lose weight at least once within the previous 3 years. RESULTS: Marital status was not associated with increased body dissatisfaction. Marital satisfaction was significantly related to body dissatisfaction when controlling for age, body mass index, self-esteem, and gender. DISCUSSION: Body dissatisfaction occurs at comparable levels among married and single individuals and the study of marital functioning among eating-disordered individuals represents a large gap in the literature.

Lesbians, bisexual women, and body image: an investigation of gender roles and social group affiliation.

OBJECTIVE: This study examined the effects of considering oneself to be masculine, feminine, or androgynous in appearance, of having friends who share one's gender and sexual orientation, and of affiliating with three subcommunities within the lesbian society on various aspects of body image. METHOD: Self-report measures were obtained from 188 lesbian and bisexual females. RESULTS: Feminine women reported lower body satisfaction than did androgynous or masculine identified subjects. Those whose friends shared their sexual orientation and gender had more positive body images than those whose friends shared only gender. In contrast, community affiliation was unrelated to body satisfaction. DISCUSSION: Within-group differences among lesbians may be central to understanding body image in this group.
